Circiuts Y8 P Flashcards
What is a electric circuit made from?
Electrical components and connecting wires.
What are the electrical components made of?
Metal because they are conductors of electricity.
Can a current flow when the circuit is open?
No, it can’t with with a open switch either.
Why are the plugs casing made of plastic? 🔌
Because it insulates electricity, so you won’t get electrocuted.
What is an electrical current?
Current is the flow of charge around a circuit.
True or false. The faster the Charge flow, the higher the current.
True
What are currents measured in?
Amps
How do you measure amps in a circuit?
Ammeter.
Will it affect the current in a series circuit if I place the ammeter anywhere?
No
True or false. The current in a series circuit depends on the number of cells
True
What is a parallel circuit?
Is a circuit there are alternative paths which is connected to a e
Element in a circuit.
If a bulb blows in a parallel circuit will the current still be able to reach the other bulb, and how?
It can still get round because there are other paths
If a bulb blows in a series circuit will the current still be able to reach the other bulb, and how?
No, it would make it a open circuit
